GPS antennas

Keep an Eye on Your Course, Data, and Security

Navigation and communication are crucial for safety and situational awareness. Interfaces like NMEA 2000/0183, suitable sensors, and correct voltage are essential.

Many systems can be expanded step-by-step – from a simple display to a fully networked setup.

This way, you get technology that truly supports you and performs reliably at sea.

Discover variants, materials, and designs built for marine use. This ensures you find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

Do I need an active or passive GPS antenna for my chartplotter?
This mainly depends on the cable length. For runs over about five meters, or if the antenna is mounted inside a hardtop, an active antenna with a preamplifier is recommended. For short cable runs and open mounting locations, a passive antenna is often sufficient.
What connector type is common for GPS antennas on boats?
Most marine plotters use an SMA or BNC connector – check your device's manual. Adapters between the types work, but on longer cable runs, they represent another potential weak point for moisture and signal loss.
Can I operate a GPS antenna on a steel hull?
Yes, but the antenna must be mounted with sufficient clearance and a clear view of the sky, as steel shields the GPS signal. A mast mount or a rail mount that positions the antenna significantly above the metal parts is the common solution here.
How do I maintain GPS antennas and cable connections so they last through the winter?
Disconnect the plugs during winterization, clean the contacts with contact spray, and protect open connections with self-amalgamating tape or connector caps. Check the cable sheath for cracks and hardening – UV and salt make insulation brittle before reception noticeably suffers.
